WOW-- Rendering 4K is really SLOOOW

My computer is only a year old and I thought it could handle it but did it disappoint me. I'm talking about 3+ hours to render less than 2 hours of 4K from my AX100. I'm wondering if I may have made some wrong selections in Sony Movie Studio Platinum during the setup.

Does anyone have experience with this s/w and are my times normal? And yes, I know that it depends on the computer but I am looking for help, not nit picking.
